What Actually Matters in a Bedroom Air Purifier

Noise Level

For comfortable sleep: under 25 dB is excellent, 25–35 dB is acceptable, and 40 dB+ is noticeable. Philips is the quietest, Levoit is very close, and Xiaomi is slightly louder but still fine for most users.

Under 25 dB → Excellent25–35 dB → Acceptable40 dB+ → Noticeable

Energy Consumption

Most bedroom purifiers use 20–50 watts in normal mode, much less in sleep mode. Running cost per month is typically very low compared to AC units.

Bedroom Size Coverage

Match your CADR rating to your room size for optimal performance. All three models handle medium bedrooms well.

Recommended CADR by Bedroom Size

Up to 20 m²	200–250 m³/h
20–35 m²	250–350 m³/h
